Sony Xperia Z2 unlocked, rooted but blank screen - Xperia Z2 Q&A, Help & Troubleshooting

Hi everyone,
I unlocked the bootloader and flashed the 'DooMLoRD' kernel. So far so good, but after rebooting the screen stays blank (black). It boots normally though. The phone is on, but no screen. Kind of inconvenient when operating a touchscreen
It looks a lot like the issue previous Xperia versions seemed to have. But the obvious fix of a hard restart doesn't work for me.
Any suggestions anyone?
Thank you!

Did you make sure you downloaded the correct kernel for the firmware version you have? ie there is a different kernel for .55 .69 & .402 firmwares.

Yes, I did. I have the .402 firmware. Unfortunately some of the screens seem to have the same issue as the Z1 issue in 2013...so I was told at the shop. I was not the only one coming in with a blank screen. Solution: I get a new phone.
Thanks for your suggestion. :good:

Solved: screen backlight died
Okay, that had nothing to do with rooting or re-flashing. Apparently the backlight from the screen died on this brandnew phone.
Went back to the store and I get a replacement... :good:

I have the same problem. Flashed different firmwares with flasher and Setool, but touch still not working.
I have read that ther is an issue with flashing the stock Kernel on some Mini and Mini Pro
As i read that i decided that i Don't try to unlock the bootloader and Flash an insecure Kernel to obtain root because it is to dangerous
Lets hope that there will be an other method to root this device

From Setool support. You must have Setool box or dongle to be able to flash/unlock sonyericsson devices.
setool3-box.org
files.setool.net/support/SETool2
So you unlocked the bootloader flashed the Kernel and then got the Same Problem like me and your solution is to Flash the older Firmware and this worked for you?

Hello all,
I'm also fighting with this problem. Has anybody more information for the reason of this bug?
My Phone:
Xperia Mini Pro SK17i 1249-0812 TYPE: AAD-3880104-BV
Bootloader is unlocked.
The Status:
My Phone is booting and all physical keys works but the sensor buttons and the Touch display is completely unresponsive/unusable.
I' ve tried different update tools (flashtool, wotan, install from CWM) and different roms:
FXP052-update-cm-7.2.0-RC0-XperiaMiniPro-SK17i-KANG-signed.7z
SK17i_4.0.2.A.0.58_(1249-7380).ftf
SK17i_4.0.2.A.0.58_GLOBAL.ftf
SK17i_4.0.A.2.335_FRENCH.ftf
also tried to update the kernel from [KERNEL] KRsH Kernel v2.0 (MiniPro)
It always results in a nearly working phone with no response from the touchscreen.
Would be very appreciative for any help!
Thanks,
Bernhard
Bought my wife a mini pro which was a SK17i
It came today and worked for about 20 minutes while I put all her stuff on it.
Then all of a sudden the touch screen and capacitive buttons stopped responding.
I had a similar issue on my x10 mini pro which related to the homebrew dual touch driver. Stock restore from SEUS fixed that.
Tried that on the xperia mini pro but it didnt help.
I've sent the phone back as faulty now.
Would be interested in hearing if the problems here are software or hardware.
Cheers
Hi guys, I have the same problem like everybody else - the touch screen doesn't work niether the capacitive buttons.
It happened when I thought I caught a virus after downloading an aplication : THE SEARCH ICON
Probably this was really stupid thought, but then I decided to make a full factory reset. My phone was rooted and after the reset the super user icon was still in the aplications. Then after 2 minutes using the phone it crushed, so I decided to unroot and then to make another factory reset and I did it.
Then the home button didn't work and the phone crushed few more times.
So I used PC Companion and update to .62. The phone was Ok for a week then it's screen and the capacitive buttons were useless.
I did 6-7 repairs from Pc Companion but still nothing.
Then I use Flashtool to flash it to SK17i_4.0.2.A.0.58_GLOBAL.ftf and again nothing. Then I flash it to SK17i_4.0.2.A.0.42_Generic_Trade_United_Kingdom_(1248-7407).ftf but still nothing. After that I updated again to .62 and no result.
IS THERE SOMEONE WHO CAN HELP PLEASE
Try Sony Ericsson Update Service to restore firmware completely.
I tried Sony Ericsson Update Service, too! Even with full factory reset and update to the latest firmware .62 and still the same problem! What should I do?
Someguyfromhell thanks you for your answer. I don't know why there are no posts for fixing this. Everybody asked for solution, but still none answer! I can't use my phone for a week now. It is really annoing . Please I really need help!
Sounds like the same problem I have. I was using hybrom + krsh kernel for months and was really satisfied with the phone. Then about a month ago the touchscreen went suddenly unresponsive for a 10 seconds or so. After that these lock ups started to became more frequent. I installed logcat and noticed it had something to do with touchscreen driver in kernel.
Next I tried bbooff's kernel but no avail. Then I used wotanserver to install stock kernel and rom, relocked bootloader, updated with pc companion, uninstalled all software I installed from market, did a 100% complete factory reset...
Then after using the phone for 5 minutes without lock ups I was really feeling victorious. I guess I forgot to knock wood because the touchscreen froze again. Now the phone is at the service center.
Either there is some really weird bug in these custom roms we all used or the hardware is bad. I never overcloked my phone more than 1,0 GHz -> 1,1 GHz so that can't be the reason.
I hope the service doesn't cost too much. I think I voided my warranty when I unlocked the bootloader and installed a custom kernel. The saddest thing is if it is a hardware problem caused by a bad hardware or a design fault I would still have to pay for it.
I understand, but it is really wierd, because I didn't use custom ROMs at all. I just made factory reset on a rooted phone (without unlocking the bootloader) after that I update to .62 from PC Companion and then I used the phone for a month and like yours the touchcsreen was dead for a little bit and the capacitive buttons, too. After that these lock ups started to became more frequent like yours. Do you thing that I will void my warranty, too and is there a solution for me?
Anyone with solution?

[Q] SK17 screen doesn't work

Today, I had the CM7.2 rom on my SK17, and it worked perfectly, I toke the phone to use it, but the touch screen didn't worked! I saw the things in the screen, but touching it gave me the same result as touching a non tactile screen! Of course, I couldn't unlock and use it.
I tried to enter the CWM mode and flash it. In the CWM the soft keys didn't worked, so I had to wait to flash again the boot.img at home with the computer.
But although I flashed again the boot.img, the touch screen didn't worked. I tried to flash other different boot.img, but it continues without work. I don't know what to do!!
Do you flash the right rom??mango??
Sent from my Xperia Mini Pro using XDA
Seen quite a lot of topics about SK17 touchscreen problems, but no solution yet, neither do we know what causes the bug.
Also, soft keys in CWM not working. I hear that first time.
Get back to fully stock ROM, might help you.
Of course I had flashed the correct rom, for mango, sk17, and I returned to the official rom too, but the problem persists.
I think it's a hardware problem, but I don't know if I should open the phone to see if something is broken...
Ok, I finally decided to take the phone to vodafone and make them solve the problem. It's under warranty yet and I think it's a hardware problem, so I won't have to pay, but I'll have to cope without my xperia during 10 days :S
Thanks for the ideas you suggested
yeah, me too having this problem.... once it worked i restored backup...but after 30minutes stopped working again.... i can change kernels...but not working..so i guess not the lib's fault here. Also softkeys doesnt work, i guess they are part of screen.

[Q] X10...dead?

Hi,
My x10 shut down today after experiencing massive battery drain. When I plugged it into the charger, it didn't restart. I've tried flashing two different kernels, the FeraKernel for GB and DoomKernel. I also tried flasing the evervolv ftf file as a last resort. No change.
Is it dead? Anything I can do?
Flash original firmware with flashtool, also try to charge the battery and check if it isn't broken.

Thanks. But when I flashed that, it wouldn't start up properly. I saw the Sony Ericsson logo for a second or two before the screen turned off again. WHen I tried to turn it on again, the red led flashed three times.
EDIT : after plugging it in, it woke up again. Looks like the X10 really won't die!
P.S you forgot to mention that that was an Eclairs ROM

From what you're indicating it sounds like your battery is dead/not holding a charge.
[a] You probably need a new battery, or charge the existing one for a good 12hrs and then see if it still holds a charge,
If not then go back to [a]
If possible you can just use SEUS (Sony Update Service) or PC Companion to flash the stock GB 2.3 Sony firmware.

Well, I have always used this ROM to repair my Xperia.
The name was 2.1, so You could have seen that it's eclair.
And if You're still having problems with phone shuting down then it's for sure the battery, I had this problem.

Screen slow to wake up

First of all, ive tried searching all morning for a fix - but so far no dice.
I have an xperia z2 that's is about 7 months old, and over the past two or three days I've started running into issues where the screen is really slow to wake up. Instead of being instantaneous when pressing the wake/power button, there is a 2-3 sec delay before the screen turns on and I can swipe to unlock.
I've tried removing the SD card (which can apparently cause this type of issue) but wanting to hear other opinions before I try messing around with wiping caches in recovery etc.
Any thoughts?
Thanks
Try reflashing your rom.
If that doesnt fix it then reflash a FTF
Ive descovered that very rarely a partition can corrupt and cause some odd lag on a device.
Forgot to mention that the screen has stopped auto-rotating as well. Are these issues likely to be connected?

as said try reflashing your Rom(if runing a custom one). if its still there try flashing A FTF.
if the problem is still there after that then the device has become defective and should be covered by warrenty. you should recieve a free repair if you call sony mobile.

[THL] W200s- Firmware- Please help!

Hello to everyone, I want to ask for your help!
First of all sorry for my bad english! I will try to explain the situation.
Last December (2014) I bought a THL W200s phone, from China. It's impossible for me to find the seller, because my uncle that was living in China for 1 year, ordered the phone via TaoBao but he doesn't remember to what seller.
Well, the phone was ok, till it fell down to the floor and the display broke.
I mean, the "outside" glass was ok, but the display wasn't.
I ordered a new phone screen in Aliexpress (ask for the link, I can't put any link here) and changed the screen.
The new screen works OK, but I've a problem. I can't get the touchscreen working.
I mean, I can see perfectly the main menu, but if I touch the screen, it doesn't "moves" or do anything, the touchscreen part isn't working.
I talked to the seller, and researched, and found out that might be a firmware problem. Something like that the screen was newer than the phone, or vice versa.
I downloaded and flashed almost all the firmwares/ROM's available in the Internet for THL W200s, that can be flashed by SP FlashTools (I can't use another method to flash because the touchscreen doesn't work), but no one worked completely.
I mean, with all the firmwares/ROM's I flash, I get the same result. Display works OK, but no touchscreen.
Except with this one : Needrom- W200S 4.4.2-KK-09/09/2014
With that one, I get the opposite result, I mean, my touchscreen works, but the display doesn't. The Phone turns on, but shows no image, it's all black, but I can feel the vibration when I press the screen and the touchscreen works OK.
I don't have experience flashing that things, or in basic Android, but I wanted to know if you can help me! I'm desperate!
I would have to "combine" the "part" or file that contains the touchscreen of that ROM (W200S 4.4.2-KK-09/09/2014) with another one, So I can finally get my display and touchscreen working.
Any ideas of how to do it? I tried replacing the lk.bin file of the ROM I mention, in some other ROM's that make my display works, but I don't get any good result.
Please, if this topic doesn't go in this forum, or if I've posted some link that can't be posted, I apologize!
Thanks for reading, if you don't understand something please ask!
PD: I've already asked to the seller for the suitable firmware, but the one that he provided, doesn't work.
Any never firmware should work. How you tried to install firmware? By FlashTool? Flash everything but preloader, it should work. To be on the safe side try latest JellyBean (4.2.2) from needrom. This could be some new screen revision but who knows. Please post your results.

First, thanks for reading!
Yes, I've tried via SP FlashTools v5.1352.01, because I think I can't flash ROM's with CWM or TWRP because I can't get my touchscreen working, so I can't install them on my phone. If I'm not right, please correct me.
As I said, I tried almost every rom that is available in NeedRom for thl w200s that can be flashed using SP FlashTools. But I can't get any good result, touchscreen doesn't work. I'm sure it's only a firmware problem, because flashing the ROM that I describe in the topic, touchscreen works but display doesn't. And flashing any other ROM display works but touchscreen doesn't.
Could you recommend a ROM to try? I don't know what else to do. I'm afraid my phone is lost
What I did to flash all the ROM's I download, using SP Flash Tools, is to select the Android scatter, then in the sliding panel clicked in "Firmware Upgrade", click in Download, connect the phone without the battery, and wait the ROM to be flashed.
I don't know what is wrong !
I had the same problem when I changed my screen.managed to use my back up I made with mtk droid tools.before I changed my screen,I was on the 4.4.2 ROM which I could now no longer use(black screen), but for some reason I could now install the ROMs from need ROM (which I couldn't use before)and the backups on my phone would freeze when I used them.only the stock ROM I had and the ultimate ROM from need ROM would work.but now the mic no longer works(tested with the google apk,phone calls and sound recorder) and the vibrate does not work and the proximity sensor does not work(tested it by using the dialer but the screen stays dark so can't end the call.so I got a dialer apk from play and that works but in the end I used a xposed module to stop the proximity sensor. really had enough of this phone.
